The distance-measuring system also includes reference optics for guiding light emitted by the light source within the system towards the light detector as internal reference light and a variable attenuator for adjusting intensity of light incident on the light detector. The variable attenuator includes an attenuating filter arranged in a beam path between the measuring optics and the light detector and an actuator coupled to the attenuating filter for moving the attenuating filter. The distance-measuring system further includes an optical selector coupled to at least one of the actuator or the attenuating filter and moved by the actuator together with the attenuating filter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distance-measuring system","description":"A distance-measuring system includes a light source, a light detector, and measuring optics for projecting light emitted by the light source to a target and for guiding light reflected from said targe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520192","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
